Perioperative Practices in Dermatologic Surgery.

BACKGROUND: Mohs micrographic surgery is generally safe and well tolerated. Various perioperative practices are employed with the aim of reducing adverse events; however, implementation is variable, and limited efficacy data are available. OBJECTIVE: This study sought to assess perioperative practice patterns among dermatologic surgeons with regards to antibiotic prophylaxis (AP), anticoagulation, activity restrictions, and antiseptic choice. METHODS AND MATERIALS: Two surveys were distributed by the American College of Mohs Surgery (ACMS) and the American Society for Mohs Surgery (ASMS) to their membership via email. RESULTS: One hundres seventy-seven surgeons participated, with membership from ACMS (61%), ASMS (35%), or both organizations (4%) represented. Systemic AP is prescribed preoperatively by 96% (162/168) and postoperatively by 91% (161/177) of surgeons for variable clinical indications. Therapeutic antiplatelet and anticoagulant medications are rarely held (3%-5%, 4-7/149), whereas preventative aspirin (30%, 45/149), NSAIDs (25%, 36/145), and supplements known to have an anticoagulant effect (54%, 80/149) are more commonly held. Antiseptic choice and recommended activity restrictions vary. CONCLUSION: Perioperative practices of dermatologic surgeons are variable and, where applicable, may deviate from guidelines. These findings underscore the need for standardization and updated guidelines for perioperative practices in dermatologic surgery.

"We Are Not Taking a Backseat": Health Social Workers' Perspectives on COVID-19 Response and Recovery.

The COVID-19 pandemic has wrought widespread devastation across the United States, exacerbating existing health inequities rooted in the social determinants of health. Social work is the key workforce tasked with providing social care in healthcare settings. In September 2019, the National Academies of Science, Engineering, and Medicine released a landmark Consensus Study Report, Integrating Social Care into the Delivery of Health Care: Moving Upstream to Improve the Nation's Health. The report describes a framework for addressing key care needs that articulates five "As for action" (5As)-awareness, alignment, assistance, adjustment, and advocacy-that are critical to social care. Drawing from a series of focus groups conducted with 55 social workers employed in a large urban pediatric quaternary hospital, this study qualitatively examines the utility of this framework in characterizing social care activities during the pandemic response and recovery efforts. Findings suggest that the 5As framework is both applicable to pandemic social work practice and an accurate encapsulation of the core elements of hospital social work practice, even if social workers themselves may not necessarily be aware of that conceptualization. Future implications for social work practice in arenas of awareness, adjustment, assistance, alignment, and advocacy are also discussed.

'We are essential:' Pediatric health care social workers' perspectives on being designated essential workers during the COVID-19 pandemic.

Continued provision of essential services is critical to maintaining society's functioning during a crisis. During COVID-19, lockdowns and restrictions designed to preserve the public's health forced an examination of what it means to be an essential worker. Drawing from thematic analyses of focus group data from 55 social workers employed in a large, urban, pediatric, quaternary hospital, this study examines the perspectives of hospital social workers on the meaning of the essential status designation of social work. Findings revealed themes pertaining the substance of social work, the ways in which essential status is carried out, and implications of the designation not only for the future of the profession but also for the populations who receive social work services. The discussion raised important questions about the essential role of social workers in broader health care settings. Our findings suggest that health care systems need to engage in ongoing discussions of how to maximize the efficacy of the social work workforce, both in terms of integration with medical teams and recognition of the important roles social workers play across the hospital system, and facilitate the performance of their essential functions.

"You never stop being a social worker:" Experiences of pediatric hospital social workers during the acute phase of the COVID-19 pandemic.

The COVID-19 pandemic has wrought widespread devastation upon children and families across the United States, widening existing health disparities and inequities that disproportionately affect communities of color. In health care settings specifically, social work is the key workforce tasked with responding to patient and family psychosocial needs, both of which have increased substantially since the emergence of COVID-19. There is a need to understand ways in which hospital social workers' roles, responsibilities, and integration within interprofessional teams have evolved in response to these challenges. In this qualitative study, focus groups were conducted with 55 social workers employed across multiple settings in a large, urban, pediatric hospital in Spring 2020. Thematic analyses revealed salient superordinate themes related to the pandemic's impact on social work practice and social workers themselves, institutional facilitators and impediments to effective social work and interprofessional practice, and social work perspectives on future pandemic recovery efforts. Within each theme, a number of interrelated subthemes emerged elucidating nuances of telehealth adoption in the context of remote work, the salience of social determinants of health, and the critical role of social work in social justice oriented pandemic preparedness and response efforts. Implications for interprofessional practice and the profession at large are discussed.

Review of environmental effects of oxybenzone and other sunscreen active ingredients.

With increasing awareness regarding the risks of sunburn, photoaging, and skin cancer, the use of sunscreens has increased. Organic and inorganic filters are used in sunscreen products worldwide. Concerns have been raised regarding the environmental effects of commonly used organic ultraviolet (UV) filters, including oxybenzone (benzophenone-3), 4-methylbenzylidene camphor, octocrylene, and octinoxate (ethylhexyl methoxycinnamate). Studies have identified UV filters such as oxybenzone, octocrylene, octinoxate, and ethylhexyl salicylate in almost all water sources around the world and have commented that these filters are not easily removed by common wastewater treatment plant techniques. Additionally, in laboratory settings, oxybenzone has been implicated specifically as a possible contributor to coral reef bleaching. Furthermore, UV filters such as 4-methylbenzylidene camphor, oxybenzone, octocrylene, and octinoxate have been identified in various species of fish worldwide, which has possible consequences for the food chain. As dermatologists, it is important for us to continue to emphasize the public health impact of excessive sun exposure and advise our patients about proper photoprotection practice, which consists of seeking shade, wearing photoprotective clothing (including hats and sunglasses), and applying appropriate sunscreens.

Emerging imaging technologies in dermatology: Part II: Applications and limitations.

Clinical examination is critical for the diagnosis and identification of response to treatment. It is fortunate that technologies are continuing to evolve, enabling augmentation of classical clinical examination with noninvasive imaging modalities. This article discusses emerging technologies with a focus on digital photographic imaging, confocal microscopy, optical coherence tomography, and high-frequency ultrasound, as well as several additional developing modalities. The most readily adopted technologies to date include total-body digital photography and dermoscopy, with some practitioners beginning to use confocal microscopy. In this article, applications and limitations are addressed. For a detailed discussion of the principles involved in these technologies, please refer to the first part of this review article.

Emerging imaging technologies in dermatology: Part I: Basic principles.

Dermatologists rely primarily on clinical examination in combination with histopathology to diagnose conditions; however, clinical examination alone might not be sufficient for accurate diagnosis and skin biopsies have associated morbidity. With continued technological advancement, there are emerging ancillary imaging technologies available to dermatologists to aid in diagnosis and management. This 2-part review article will discuss these emerging technologies including: digital photographic imaging, confocal microscopy, optical coherence tomography, and high-frequency ultrasound, as well as several additional modalities in development. In this first installment, the authors describe the breadth of technologies available and the science behind them. Then, in the second article, the authors discuss the applications and limitations of these technologies and future directions.

Differential effect of Hurricane Sandy exposure on PTSD symptom severity: comparison of community members and responders.

OBJECTIVES: To evaluate whether the association between Hurricane Sandy exposures and post-traumatic stress disorder (PTSD) symptom severity was greater for exposed community members compared with responders. METHODS: Data were analysed from three existing studies with similar methodologies (N=1648): two community studies, Leaders in Gathering Hope Together (n=531) and Project Restoration (n=763); and the Sandy/World Trade Center Responders Study (n=354). Sandy-related PTSD symptoms were measured using the PTSD checklist-specific traumatic event and dichotomised as elevated (>30) versus low/no (<30) PTSD symptoms. Sandy exposures were measured with a summed checklist. Multivariable logistic regression was performed to evaluate the differential effect of exposures on PTSD by responder status, adjusting for demographics and time elapsed since Sandy. RESULTS: Responders were somewhat older (50.5 years (SD=8.3) vs 45.8 years (SD=20.0)), more likely to identify as white (92.4% vs 48.1%) and were male (90.7% vs 38.4%). Responders were less likely to have elevated PTSD symptoms than community members (8.6% vs 31.1%; adjusted OR=0.28, 95% CI 0.17 to 0.46). While exposure was significantly related to elevated PTSD status, the effects were similar for responders and community members. CONCLUSIONS: Responders appear to be more resilient to PTSD symptoms post-Sandy than community members. Understanding the mechanisms that foster such resilience can inform interventions aimed at populations that are more vulnerable to experiencing PTSD after natural disasters.

A review of inorganic UV filters zinc oxide and titanium dioxide.

Photoprotection has become integral in the prevention of keratinocyte cancer and photoaging. Organic ultraviolet (UV) filters such as oxybenzone and octinoxate have become controversial due to their potential impact on the environmental and their potential human health risks. As such, inorganic UV filters, zinc oxide (ZnO) and titanium dioxide (TiO2 ), have become paramount in discussions about photoprotection. ZnO and TiO2 are used in sunscreens as nanoparticles, which denotes a size <100 nm. The smaller size of these mineral particles increases their cosmetic acceptability by users as they are much less visible after application. ZnO has a broad UVA-UVB absorption curve, while TiO2 provides better UVB protection. Overall, the human health risks with inorganic filters are extremely low given a lack of percutaneous absorption; however, there is potential risk when exposed via inhalation, prompting recommendations against spray sunscreen products with nanoparticles. At this time, the known risk to the environment is low though the risk stratification may evolve with increasing usage of these filters and higher environmental concentrations. The continued practice of photoprotection is critical. The public should be counseled to seek shade, use photoprotective clothing including hats and glasses in addition to sunscreens on sun-exposed skin. For those concerned about emerging evidence of environmental impact of organic UV filters, based on current evidence, ZnO and TiO2 -containing sunscreens are safe alternatives.

Engagement in linkage to mental health care program in the Rockaways after Hurricane Sandy.

The Rockaways area of New York City was especially devastated by Hurricane Sandy. This study examined participant characteristics associated with acceptance of a linkage to and attendance at appointments for mental health difficulties (MHD). Participants (N = 1,011) completed questionnaires to assess mental health symptoms. Participants who met screening criteria (n = 442) were offered linkage to care. Individuals who had a higher mental health symptom burden (MHSB; i.e., those who screened in on more than one criteria vs. only one criterion) had 2.68 greater odds of accepting services (95% confidence interval [1.68, 4.26]). MHSB was not associated with attending a first appointment (p = 0.80). Female gender and Hispanic ethnicity were also associated with acceptance of linkage to care, though not attendance. Reducing stigma around MHD associated with natural disasters and increasing knowledge about the mental health care system could promote help-seeking behavior among survivors.

Cutaneous manifestations of metastatic Crohn's disease.

Metastatic Crohn's disease is a rare cutaneous complication of primary Crohn's disease. It is a granulomatous inflammatory process, similar to the pathogenic mechanism of Crohn's disease, that occurs in sites discontiguous from the gastrointestinal tract. Metastatic Crohn's disease can precede the development of Crohn's disease by months to years, and children are more likely to present with metastatic Crohn's disease in the absence of gastrointestinal symptoms. Given that approximately 30% of individuals with Crohn's disease present in childhood, early recognition of extraintestinal manifestations of Crohn's disease such as metastatic Crohn's disease can aid in timely diagnosis and management of bowel disease. We present data from two pediatric cases of metastatic Crohn's disease recently seen at our institution in addition to the 61 reported cases of pediatric metastatic Crohn's disease in the literature. This review article will focus on the epidemiology, pathogenesis, clinical features, and histology of and treatment options for pediatric metastatic Crohn's disease.

Wilderness dermatology: mountain exposures.

Exploring the mountains is a highly rewarding past time; however, certain high-altitude exposures can lead to dermatologic manifestations. In this review article, the authors will describe cold, solar, and severe weather that one may experience when spending time outdoors. Factors such as increased ultraviolet radiation, temperature extremes, and low partial pressure of oxygen, along with human physiologic parameters also contribute to disease severity and presentation. This review article will address the diagnosis, treatment, and prevention of high-altitude dermatology exposures.

Clinical, dermoscopic, and pathologic features of onychopapilloma: A review of 47 cases.

BACKGROUND: Onychopapilloma is a benign neoplasm of the nail bed and the distal matrix. Although not uncommon in our experience, only up to 32 cases of this tumor have been reported in the literature. OBJECTIVE: We sought to review the clinical, dermoscopic, and pathologic features of onychopapilloma. METHODS: We retrospectively analyzed the clinical features of 47 patients with pathologically confirmed onychopapilloma diagnosed within the last 5 years, and reviewed the published literature. RESULTS: The most common clinical presentation was longitudinal erythronychia (n = 25); followed by longitudinal leukonychia (n = 7); longitudinal melanonychia (n = 4); long splinter hemorrhages without erythronychia, leukonychia, or melanonychia (n = 8); and short splinter hemorrhages without erythronychia, leukonychia, or melanonychia (n = 3), with subungual mass (n = 47) and distal fissuring (n = 11). Pathology was consistent with acanthosis of the nail bed and distal matrix, with matrix metaplasia underlying distal subungual hyperkeratosis. LIMITATIONS: This was a retrospective analysis. CONCLUSION: To our knowledge, our series of onychopapilloma is the largest so far. Among various clinical presentations, longitudinal erythronychia is the most common. Dermoscopy of the free edge of the nail plate showing a small subungual keratotic mass where the band reaches the nail plate margin provides a clue for the diagnosis.

Do inflammatory pathways drive melanomagenesis?

Inflammatory pathways serve to protect the host and promote tissue healing/repair; however, over-activation or dysregulation can be pathological with unintended consequences including malignant progression. A correlation between inflammation and cancer has been well established, and anti-inflammatory medications have been shown to be chemopreventive in certain malignancies. Data are now becoming available that outline an inflammatory pathway that may have a critical role in melanomagenesis. ATP-regulated membrane channels/receptors P2X7 and PANX1 have been directly implicated in melanoma tumor growth. Among other potential effects, opening of the P2X7/PANX1 channel results in activation of the NALP3 inflammasome, which in turn leads to caspase-1 activation and increased levels of activated IL-1ß. Elevated levels of caspase-1 and IL-1ß have been correlated with melanoma progression, and inhibitors of the inflammasome, caspase and IL-1ß activity have all been shown to inhibit melanoma growth. Among many other potential actions, IL-1ß increases cyclooxygenase-2 expression leading to local increases in inflammatory mediators such as prostaglandin E2 (PGE2). Anti-inflammatory medications targeting the end of this pathway have had positive results for certain cancers but overall remain mixed for melanoma. A better understanding of the pathways and appropriate intervention points may help direct future therapies. In this viewpoint, we will review data and attempt to model an inflammatory pathway that may be critical for melanomagenesis and propose future directions for exploration.

Chromoblastomycosis in a Diabetic Patient Without a History of Trauma.

Chromoblastomycosis (CBM) is a slowly progressive cutaneous and subcutaneous mycosis mostly seen in tropical and subtropical areas and Fonsecaea pedrosoi is the most common cause. The authors describe the case of a diabetic Haitian woman, presenting with a chronic verrucous plaque without any history of trauma. Her histopathologic results showed epidermal hyperplasia and sclerotic bodies, which are diagnostic for CBM. Her therapy began with itraconazole 200 mg tablets twice a day. The unique feature of this patient is the coincidence of diabetes and CBM. However, to the best of our knowledge, this is the first documented case of human CBM in Miami, FL, which develops the awareness regarding this diagnosis among doctors in this area. There should be a close communication between dermatologists and pathologists to make an early diagnosis of CBM and also adequate therapy, which both are fundamental to improve patient's quality of life.

How, and from which cell sources, do nevi really develop?

Melanocytic neoplasms are a diverse group of benign and malignant tumors with variable clinical features. While some models still promote the epidermal melanocyte as the origin of melanocytic neoplasms, clinical findings are inconsistent with this theory for the majority of tumors. Despite advances in naevus and melanoma biology, the location and differentiation status of the cell of origin remains undefined. Germ line genetics, biological state and cellular location of the mutated cell, as well as local environmental factors all likely play a role in the development of melanocytic neoplasms. Herein, we will review potential models for melanocytic neoplasia and discuss research challenges and opportunities.
